So my Nissan Silvia s15 has a ton of problems, and I'm worried my budget is going to go overboard. Basically, when I reversed the car it would turn off and it turns out 2 cylinders or whatever is not working and the spark plugs were completely messed up on 2 of them. They were very black and the one cylinder that worked, the spark plugs metal thing on the tip of it actually was broken off but still working. Anyways, replaced spark plug and batteries still the same issue.
When I turn on the car and let it run and even when it's warm it has a knocking like sound. Compression is low as mentioned first cylinder is 120, the second is 145, the third is 128, fourth is 145
I noticed the oil is THICK as hell, I went to drain some and it took quite a long time, maybe this was so the sound of the knocking isn't so rough? And lastly, when trying to put the car into reverse it's a bit of a challenge as it has a bit of a problem going into reverse gear (I think the clutch is gone). Just looking at what the problems could be. Here is a clip of the sound of the engine. Also the spark plug leads all seem to be fine.
I added some oil to pistons and they went up from 120 to 140, so the piston rings are probably gone. Getting genuine parts is going to cost me thousands and I can't afford that. Not to mention I don't even know if the engine block is damaged, if it is I'm screwed. What is my cheapest option here? I was hoping to just replace the head gasket, clean the carbon build up on the pistons, and replace the rings with after market ones.
Worth noting the muffler is all black as it spat out some petrol. Needed some advice urgently on what to do, what are my best options?
